This is my second 308 and it does not hold the car. I guess I need to spend sometime cleaning it up to work correctly. Thanks Birdman
I know it's in the archives, but here it is again... Ric Rainbolt's instructions which DO WORK!! I had the problem for the first 8 years of owning my car, but this fixed it. ========================== OK, the 308 handbrake should hold aa mild incline. That much is certain. If your parking brake is ineffective, it can be corrected, but it may take a little work to get there. If starting from an unknown state, I would do the following: 1) Jack the car up and place it on jack stands. 2) Remove both rear wheels and release the parking brake. 3) On US-spec cars and some others, you have to remove a flat metal underpanel to gain complete access to the parking brake cable. This panel is held on by four 10mm bolts. 4) Find the cable that runs between the calipers. We'll call this cable "A". It should route through low friction "eyes" (or cable guides on early 308's), mounted on each side of the car, on it's way to the calipers. The eyes are either nylon or brass, depending on production at the time (or in some cars, a simple metal tube). Refer to the parts book if uncertain. 5) Note that in the middle of the undercarriage, cable A runs through a two-wheeled lever mechanism. It's quite common for the cable to jump off a wheel and/or become severely frayed at this point. Clean this assembly VERY thoroughly and lubricate with a cable lube or synthetic grease. I usually remove the assembly so I can check the operation of the wheels. 6) Locate the buckle on cable A. It should be between the two-wheeled lever and the right side caliper. Two open end wrenches are required to operate the buckle (10mm?? I forget). Loosen the stop nut and the cable adjustment is made by turning the long part of the buckle. 7) At this point, loosen the buckle until it begins to "slack up". That is, until the caliper levers quit pulling, but not so much that the cable falls off the calipers! 8) Inspect the condition of all four rear brake pads. If necessary, remove the pads from the calipers. You'll get the best parking brake effect from a new set of pads. Also, make sure the rotors are not warped. 9) With the pads installed in the calipers, it is necessary to set the take-up adjustment within the caliper. This is accomplished by removing the two covers over the adjusting ports. On the outside of the caliper, normally, there is a plastic cap covering an adjuster. On the inside, there is a cap head plug, just under the parking brake lever along with a copper gasket. If it's the original ATE plug, it can be a ***** to get out. What I've done to get the inner cap off is actually use a punch to "drift" the cap in the counterclockwise direction. I use a stainless steel cap to replace it when done. If a significant amount of fluid is released when the inner cap is removed, the calipers need to be rebuilt. 10) The outer adjustment is kind of tricky. You must loosen the locking nut (12 or 13mm, I think) to turn the adjustment (4mm hex wrench). Place a .004 inch (0.1mm) feeler gauge between the pad and the rotor and adjust the take-up until the feeler just slips out. It should not drag significantly. Check that the feeler feels about the same at the top and bottom of the pad area. If its drastically different, either the pads are tapered, the rotor is warped, or the caliper is not true. 11) Once the outer pad spacing is set, tighten the locking nut. The problem here, however, is that tightening the locking nut has the effect of altering the adjustment. You have to play with it a little bit to figure out what's going on. After a bit you'll develop a feel for it and you should be able to lock it right at the right point (.004 inch clearance). After everything is tight, double check with the feeler. 12) The inner adjustment is easier because there is only an allen head adjuster (up inside the hole that the cap plug covered, 4mm I think). Using this adjuster, set the inner pad to the same spacing as the outer (again, .004 inch). If the adjuster feels "crusty", shoot some WD40 up in there and turn it back and forth to break loose any corrosion or dried lubricant. 13) After setting the adjustment, replace the inner cap and copper gasket. 14) Tighten the buckle on Cable A until the levers on the caliper *just begin to move*. Any more than this can cause the brake pads to drag, causing premature pad and/or rotor failure (not to mention stinky smoke!). If in doubt, check the pad clearance afterwards and re-adjust. 15) Check the lever "feel" in the car. It should only click 3-4 times before becoming fully firm. If not, have someone help you while you observe the 2-wheeled lever under the car. The 2-wheeled lever should begin to pivot just as the parking brake handle is pulled. If not, there's excess slack in the cable that runs from the handle to the lever. The slack can be adjusted in the cockpit by opening the zipper on the leather shroud. Looking in with a flashlight, to the right side (passenger side on US cars) of the lever there's a nut that can be turned to adjust cable slack. 16) Reassemble the car (underpanel, wheels, etc.). Whew. That's all. I know it sounds like a lot, but once you figure it out, it's all fairly easy work. Regards, Ric Rainbolt
AWESOME JOB!!!!!!!!! LOOKS LIKE IT WAS ALOT OF FUN .QUESTION ,WHERE DID YOU GET ALL THE INFO ON THE MARKING ON THE INDIVIDUAL PARTS ,NUTS ,BOLTS ,INNER FENDERS ETC!!! SURE WOULD LIKE TO KNOW . PLEASE E-MAIL ME WITH ANY INFO. AGAIN AWESOME JOB!!!!!!!!!!!!!!!!!!!!!!
Fortunatly my car was very original to start with and all the markings were intact. This combined with a lot of research allowed me to be confident in all the markings and their placement. I also took a lot of pictures before disassembly in order to be sure of everything. If you look in some of the pictures I posted, the markings are visible and it was a matter of just copying them once the parts were re-finished. Getting the inner fender writing correct took a lot of practice and my shop was covered in pieces of cardboard with '96A' on them.
I see a lot of silver color, but aren't 308 brake calipers and a lot of the suspension parts gold cad? I know on my BB512i the brake calipers and control arms are gold cad, not silver. I would have thought that since the 308 was made at the same time as the Boxer that its suspension parts would be finished the same color? Maybe not?
Most of the plating including the calipers is indeed gold cad plated. Some parts were silver cad and fortunatly all the parts that came off were sufficiently intact from original to be able to definativly identify the plating colours. The flash from my camera did wash out some of the colours but in person they are vibrant.
Excellent work. Just some small items I thought I would mention. I noticed you painted your nuts (the ones on the car, hehe). After all that work, the CV joint nuts didn't get painted, and they are THE most prone to back off of all! I've found that if you don't use Blue Loctite on the CV bolts, you're just asking for additional work. Also, I can't tell from the photos, but make sure the brake lines don't come in contact with anything throughout the range of suspension and steering movement. The braided outer sleeve with "file" away anything (I mean ANYTHING) that it comes in contact with. If in doubt, you can get a plastic spiral covering to guard against this.
Thank you for the compliments Ric. It means a lot coming from someone with your extensive Ferrari service background. With regards to the points you brought up, I used blue Loctite on the CV bolts but did not paint the nuts because I could not find evidence of them ever being painted from the factory. The braided lines luckily do not touch anything in sight. As an aside, the Goodridge lines have a really nice clear plastic sheathing over the hoses. This too would cut back on chaffing from accidental rubbing.
Would you be interested in doing this with mine...I am not as skilled.......But I am in Canada as well....?
Wow talk about a blast from the past in resurrecting a thread that is close to 14 years old. Regrettably I have too many ongoing projects to take on any more but you are welcome to message me for any advice you may need.
Thanks - Would you mind forwarding your personal email/Phone number? ....Easier to communicate that way....
